Healthcare diagnostic software

I am considering developing medical software that will provide patients with advice on whether they need to go to the hospital or not. The software will also provide them with the most probable diagnosis along with basic at-home treatment options. I am looking for a more accurate version of ADA for medical diagnosis, with the primary target population being the UK. I need assistance from AI to develop the algorithm for medical diagnosis. It will also include advice for long term medical conditions and information on general problems. I envision an app where users input their symptoms to receive accurate diagnoses based on current medical knowledge. It should provide basic at-home treatment options, as well as guidance on whether to visit a hospital or urgent care. The app must include general information about common diseases and management of long-term health issues. Data from reliable sources is crucial for the app's credibility. Incorporating up-to-date research from medical databases like UpToDate ensures evidence-based guidelines are followed. Designed like a chatbot, it narrows down differential diagnoses based on user-provided information such as acute abdominal pain. The app then offers practical advice: rest at home, consult with a GP, visit urgent care or go directly to the hospital. Additionally, it should suggest appropriate pain relief measures. Ultimately, this AI-integrated software requires an extensive vocabulary and algorithm-driven diagnostics that closely replicate those provided by healthcare professionals
